A light microscope image of dissected Drosophila ovary where DNA (white) reveals perfectly round nurse and follicle cell nuclei of intact egg chambers in addition to bright-staining, condensed fragmented DNA from apoptotic nurse cells expressing activated caspases (red). The outline of egg surfaces is labelled by wheatgerm agglutinin (green). Predatory wasps inject their eggs into Drosophila larvae, but adult female flies can see the predator, or simply be informed by other flies exposed to wasps, and flies deprive this predator of larvae by triggering death of its own oocytes and halting egg production.
